Key: OGM-10

Project: Hibernate OGM
Issue Type: Task
Reporter: Emmanuel Bernard
Fix For: 1.0-next
From what Manik said recently, they do marshal data when putting it in
the map and thus a copy on read is not necessary.
Clarify that and make sure mutable types do a proper copy on read if that's not the
case.

Sanne Grinovero commented on OGM-10:
------------------------------------
what Manik was referring to is a feature which needs to be enabled, not something
Infinispan does in all cases.
The code relevant to this value copy is in org.infinispan.marshall.MarshalledValue, and
its current implementation is just a performance detail, in no case (with no
configuration) you can mandate the MarshalledValue to guarantee the return of a new copy
for each invocation: two concurrent get() operations might retrieve the same instance with
the current locking granularity.
We could change Infinispan's implementation to provide such a feature, but something
like this would need to be reimplemented for other dialects anyway so I guess we have to
make copies for non-immutable values which are exposed to user API (or otherwise
modified)

Sanne Grinovero commented on OGM-10:
------------------------------------
It would be relatively simple to patch Infinispan to always make an instance copy on read
(introducing an option for that), but I'm suspecting that's not exactly what OGM
needs.
Assuming one is only storing safe primitives and immutable types such as String, one might
want to avoid unneeded and costly copies. But this might still be needed for example for
Date, unless it's mapped as a long. Are we going to need such an option on a "per
property" base?

-------------------------------------
No I was thinking of a global setting but it might not be a concern to leave the current
implementation (ie mutable grid types copy) and Tuples are left to the grid dialect.
